Is there any truth to star signs and palm reading and that kind of stuff?

None. "Astrology" is one of the so-called "mysteries" with roots in the ancient world. It is actually just a means of thought control, by teaching people to think of themselves in arbitrary definitions and behavioral expectations.

The time of your birth means nothing. Stars, planets, moons, etc. millions upon millions of miles away have zero - ZERO - objective influence on your life, your choices, your destiny.

Remember that at one time it was humans who made all these "signs" up and decided when they would be placed on the calendar, and what they would "mean", etc. etc. etc. - meaning they invented it all, no starcharts, no divine communication, no astral knowledge, nothing. Just imagination.

"Astrology" is as much a real science as alchemy or divination, which is to say it's not real at all, except in the sense that people who believe in it allow it to rule their lives. Same old thought control.

No.

It's a belief system, there is some truth to it as anything said is bound to happen to some people, however it is nothing more than guess work. Palm reading however is 100% a scam, preying on people's beliefs to extort money out of them. There's a reason fortune tellers are always at carnivals, they're just as much of a scam as those who glue skittles together so you can't knock them down or bend the barrel of the gun sight so that you can't aim it properly.

yes

When done correctly, yes.

Yep.
